Definitions
- the present invention relates to a biodegradable device with a slow release of volatile products which attract insects.
- the present invention relates to a biodegradable device which supplies pheromones for attracting male insects.
- Pheromones have become of great importance in research for new methods for controlling insect species which are harmful to agrarian crops; compared with conventional products, these substances have the advantage of a high selectivity towards a particular species or a limited number of similar species, without influencing non-harmful or useful fauna.
- sexual synthesis pheromones are used both for supervising the population development of parasites and also for directly controlling harmful species preventing their mating.
- the first type of application allows the population fluctuations of parasites to be followed, by periodically checking their capture in specific traps, observing their biological cycle to enable the possible approach of the "damage threshold" to be predicted and deciding when to intervene, also with conventional fighting systems.
- the sexual pheromones can either partially or totally substitute insecticides and directly control the harmful species by interfering with their reproduction activity.
- the first consists in attracting and subsequently capturing as many adult insects as possible by means of specific traps using pheromone as bait.
- the second technique is effected by saturating the environment with large quantities of active ingredient (not less than 75-100 g/a.i./ha), in order to shield the natural call of the females and thus preventing the males from identifying them.
- the third technique consists in creating traces of pheromones predominant over the natural call of the female insects, by the distribution of a sufficiently high number of diffusers with a reduced quantity of active ingredient.
- the male insects are therefore busy following false pheromone traces and spend most of their time visiting the various supply points instead of the females present in the area to be protected.
- the male insect is not only unable to recognize the natural call of the females but cannot even follow the artificial call emitted from the monitoring traps installed inside the lot of land treated. This allows easy control of the effectiveness and persistency of the treatment: in fact, in the presence of confusion or disorientation, captures in the traps must be annulled.
- diffusers are used, whose active ingredient is incorporated in different kinds of substrates which regulate its release and persistency.
- This system is effected, for example, with capillaries having one end open from which the active ingredient is volatized (U.S. patent 4,017,030).
- biodegradable plastics which are available in 1998, as starch filled thermoplastics, such as LDPE, LLDPE, HDPE, ethylene-acrylic acid copolymers, starch-g-PAN graft copolymers, polyester based polyurethanes.
- EP 0816430 discloses a biodegradable sustained release preparation which comprises a mixture of: from 99 to 10 parts by weight of an aliphatic polyester and from 1 to 90 parts by weights of a modifier for the regulation of sustained releasability of an active ingredient.
- EP 0402826 refers to a process for the preparation of a polar ethylene copolymer filled with from 5 to 90% by weight of a non fibrous carbohydrate, by extrusion of a mixture of the components and the use of the so prepared material as pheromone dispenser.
- JP-A-04-230602 discloses compositions containing a macromolecular material carrying pheromone with a biodegradable or photodegradable degradation accelerator (or their mixtures) added at 1-40%.
- US 4,842,860 discloses a process for producing a controlled release preparation which volatilises drugs or active ingredients such as pheromones.
- the process comprises the steps of mixing a resin with a carrier, impregnating the resulting mixture with an active ingredient and compressing the mixture to form a solid.
- the resin is selected from the group consisting of polyethylene, polypropylene etc.
- the device consists of a substrate of fibers and/or fibrils containing a pheromone adsorbed or dispersed therein, partially coated with a layer either completely or moderately impermeable to the pheromone, consisting of aluminum, nylon, polyester or polyvinyl chloride film.
- the objective of the present invention is therefore to produce a biodegradable device which allows the slow and controlled release of the pheromone into the air and which has a disorienting action with respect to insects.
- an injection moulded device for fighting against insects consisting of a biodegradable material based on starches and thermoplastic polymers containing a pheromone or mixture of pheromones, wherein the pheromone or mixtures of pheromones is specific for each of the following insects: Cydia molesta , Anarsia lineatella , Cydia funebrana , Cydia pomonella , Lobesia botrana , Spodoptera littoralis , Heliothis armigera and the content of pheromone or mixtures of pheromones ranges from 0.5 to 2% by weight.
- the pheromones which can be used derive from alcohols, acetates and aldehydes containing from 10 to 18 carbon atoms, mono-, bi- and tri-unsaturated and their mixtures, such as for example pheromones of Cydia molesta , Anarsia lineatella , Cydia funebrana , Cydia pomonella , Lobesia botrana , Spodoptera littoralis , Heliothis armigera .
- the device of the invention can also be used for the controlled release of other volatile products useful in the fight against insects such as Trimedlure®, for example.
- This product which is sold by Chem Progress S.r.l. has an attracting function with respect to fruit flies, Ceratitis capitata, and can be used for the production of both monitoring and mass capture traps.
- thermoplastic polymers Any biodegradable material based on starches and thermoplastic polymers can be used for the production of the device of the invention.
- Materials based on maize starch capable of being rapidly biodegraded or composted can be used, which can be extruded or moulded under not excessively drastic temperature conditions and with reduced moulding times, in order to protect the pheromones incorporated therein.
- the device can have any form suitable for application on site, such as envelope, rod, spiral or hooked with an elongated stem.
- the release rate of the pheromone is influenced by the thickness of the material used for producing the specific forms.
- Materials having a diameter ranging from 2-5 mm generally allow acceptable release rates, whereas optimum rates are obtained with materials having a diameter ranging from 3 to 4 mm.
- the device of the present invention can be prepared by impregnating granules of the biodegradable material with the pheromone in a horizontal mixer.
- the pheromone can be used as such or in a solution of suitable solvents.
- solvents which can be used are: methanol, glycerin, maize oil, white mineral oil, saturated alcohols containing from 10 to 14 carbon atoms and their acetates.
- the mixing is carried out at temperatures ranging from 20 to 40°C and for a time varying from 30 minutes to two hours, preferably from 45 to 60 minutes.
- the impregnated granules are subsequently injection moulded into the various forms, at temperatures ranging from 100° to 200°C, preferably from 140° to 160°C.
- Stabilizers and antioxidants can be optionally added to protect the active ingredients from atmospheric agents and dyes, for the differentiation of the pheromones of the various species of harmful insects.
- the pheromone content for each diffuser ranges preferably from 0.7 to 1%.
- a number of diffusers are installed per hectare ranging from 1300 to 3000, preferably from 1500 to 2500.
- the quantity of active ingredient thus used ranges from 6.5 to 60 grams per hectare, preferably from 10 to 25 g/ha.
- the theoretical pheromone content is therefore 0.999 grams per 100 grams of granules.
- Samples of granules thus impregnated are accurately weighed and analyzed to determine the actual quantity of pheromone contained therein, as described in Example 4.
- the remaining granules are injection moulded at a temperature of 140°C into spiral and hooked forms with an elongated stem (see fig. 1 a-b).
- the end-products obtained are subsequently analyzed to determine the actual quantity of pheromone contained therein, as described in Example 4 below.
- Granules of Mater-Bi having different compositions are impregnated with pheromone for Cydia molesta according to Example 2, extruded into rods having a length of 10 cm, a diameter of 3 mm and a weight of 1 gram.
- Each diffuser thus obtained contains an average of 1% by weight of pheromone, except for sample F 0.5 which contains an average of 0.5% by weight of pheromone.
- the diffusers are exposed in mid-field, periodically removed at pre-selected times and analyzed according to Example 4.
- Granules of Mater-Bi grade ZF03U/A are treated in a horizontal mixer equipped with screw blades with a pheromone mixture for Cydia molesta, for 60 minutes at room temperature.
- the granules are then injection moulded into hook form with an elongated stem (Fig. 1c) and the diffusers obtained have an average content of 1% by weight.
- the diffusers are exposed in mid-field, periodically removed at pre-selected times and analyzed according to Example 4.
- Figure 3 indicates the release kinetics.
- Example 6 The same procedure is adopted as described in Example 6, but using the pheromone for Anarsia lineatella, consisting of E5-decen-1-yl acetate and E5-decen-1-ol (in a ratio of 82:18).
- the diffusers are exposed in mid-field, periodically removed at pre-selected times and analyzed according to Example 4.
- Figure 4 indicates the release kinetics.
- the diffusers obtained have an average content of 1% by weight of each pheromone.
- the diffusers are exposed in mid-field, periodically removed at pre-selected times and analyzed according to Example 4.
- Figure 5 indicates the release kinetics.
